Aim: Failed cranioplasty attempts may lead to numerous complications in a broad spectrum including cosmetic problems, infection, neurological deterioration and even death. Selection of the most appropriate surgical technique for second and further surgical attempts for these patients still remains a debate. We aimed to share our experience and technical pitfalls on management of failed cranioplasty, particularly for patients with large cranial defects.
Material And Methods: A retrospective data analysis of cranioplasty cases in our series was performed including the time period between 2002 and 2012. Patients required recurrent cranioplasty were analyzed in detail.
Results: Totally, 101 patients underwent cranioplasty for bony defect. Of 101 patients, eleven required a revision surgery due to infection or spontaneous resorption of the bone flap. All patients underwent revision cranioplasty with pre-surgical plaster cast mold technique modified from previous studies and/or tissue expansion technique. Polymethyl-metacrylate (PMMA) was used as substitute for reconstructions. Mean follow-up was 36 months. Two out of eleven cases (18.1%) developed major complications, which led to further revision. At the end, a satisfactory reconstruction was achieved for all patients.
Conclusion: Our modified molded plaster cast technique is a safe and cost-effective approach for the revision of failed cranioplasty. We believe that the tissue expanding techniques have also great contribution to achieve successful results.

Scalp reconstruction, particularly with complex defects and infection risks, often favors microvascular free flaps. However, this method can result in unavoidable alopecia and undesirable aesthetics. This report describes a novel case where hair transplantation via follicular unit extraction (FUE) was applied to a free myocutaneous flap.

BACKGROUND Decompressive craniectomy is a common life-saving intervention in the setting of elevated intracranial pressure. Cranioplasty restores the calvarium and intracranial physiology once swelling recedes. Cranioplasty is often thought of as a low-risk intervention.

Background: Postoperative intracranial neurosurgical infections (PINI) complicate < 5% neurosurgeries. Scarce attention was dedicated to the extension and characteristics of its antimicrobial management considering their high morbidity, not negligible mortality, delayed hospital stay and increased healthcare costs.
Methods: We analyzed retrospectively (2014-2023) 162 PINI from eight Spanish third-level academic hospitals.
Revision Cranioplasty with Three-dimensional Custom-made Titanium Implants in Patients with Failed Cranioplasty.

Article Synopsis
- Graft failure is a frequent issue in cranioplasty, necessitating revision procedures, and this study explores outcomes using custom-made 3D titanium implants for such revisions.
- In a review of 43 patients from 2011 to 2019, those with initial polymethyl methacrylate (PMMA) implants experienced a longer duration before needing revisions compared to those with autologous grafts (AG), without significant differences in hospital stay length.
- The findings suggest that while PMMA leads to longer timeframes before revision compared to AG, both show similar hospitalization results, and custom-made 3D titanium implants prove beneficial in reducing implant failure and addressing cosmetic issues.

Introduction: Penttinen premature aging syndrome is caused by mutations in the PDGFRB gene. We describe the case of a 10-year-old girl with a de novo c.1994T>C variant in PDGFRB who developed multiple cranial, intracranial, and spinal manifestations, including macrocephaly, enlarged convexity subarachnoid spaces crossed by numerous vascularized arachnoid trabecule, hydrocephalus, spinal epidural lipomatosis, a low conus medullaris, calvarial thinning with large anterior fontanelle, and a skull fracture with bilateral epidural hematomas.
